Patent GB-292554-A (GB)
Abstract: 292,554. Siemens &. Halske Akt.-Ges. June 22, 1927, [Convention date]. Factory and like time recorders, card type.-An apparatus for registering the working time or other values in connection with works operations, stores administration, &c., comprises a set of perforating stamps and control levers influenced by one or other of a pair of sets of control discs controlled respectively by a clockwork or other automatic counting device and by manual manipulation. The machine, as shown in Figs. 1 to 4, is adapted for registering the starting and finishing time of a job of work, a special feeling and perforating device being provided for distinguishing negative registrations from positive registrations. The perforating stamps or punches 4 are arranged in a row in groups of four with valves 1, 2, 4, and 8 so that one or a combination of punches when operated perforate a recordcard and record - strip in accordance with the digits of the decimal system. The punches 4 are operated by the interposition of members 14, pivoted on control levers 13, between the heads thereof and hammer levers 5 operated by staggered cams 3 on the main operating shaft 1. The levers 13 are rotatably mounted on a shaft 20 and have projections 21, 22 for co-operation with sets of control discs 28, 43 respectively and a downwardly extending arm connected by means of a spring to a yoke member 24 fixed on the shaft 20. The shaft 20 is rocked, to move the levers 13 and members 14, by an arm 25 secured to the said shaft and operated by a cam 8 on the main operating shaft. The control discs 28 are mounted on a shaft 30, those of the lowest order being fixed thereto and the shaft 30 is geared to a shaft 40 actuated by clockwork mechanism. When these automatically controlled discs 28 are effective the discs 43 are in such a position that the notches thereof are opposite the projections 22. When the control of the punching is to be effected by hand the discs 28 and shaft 30 are displaced axially to be out of operative position by rocking a shaft 36 to which is fixed an arm 39 co-operating with a pin 38 on a spring-controlled lever 35 loose on the shaft and provided with an inclined surface engaging the end of the shaft 30. The shaft 36 is rocked by a yoke lever 47 thereon engaging the manipulative levers 46 each of which carries a gear segment 45 for setting the control discs' 43. The controls discs 28, 43 of the various denominations are connected together by transfer mechanism of known form. In order to distinguish values of opposite signs a special punch 51 in line with the punches 4 and a feeling pin 53 secured to a pivoted lever 52 is provided. The lever 52 has a projection 54 co-operating with a pin 55 on the member 14 of a special lever 13. If the pin 53 in operation meets the record-strip surface the projection 54 engages the pin 55 and prevents movement of the member 14 so that the punch 52 is not operated. If, however, the feeling pin 53 passes through a previously made perforation the member 14 is released and the punch 52 operated to produce the special perforation. The amount of insertion of the record card 17 is regulated by a cutting device 56 clipping the edge of the card and the advance of the duplicate record-strip 18 is governed by a pawl 63 on the lever 25 and a ratchet wheel 65 on the winding up spool 58. The operating handle is held in the normal position by a spring controlled ball in a housing 10 engaging one of the recesses of the cam 8.
